Distribution characteristics of zooplankton in the south part of Taiwan Strait in summer

Based on the samples collected mesoplankton net from the south part of Taiwan Strait (22.25°-24.65°N, 117.50°-120.00°E) in August 1997,292 species of zooplankton and 11 groups of meroplankton were identified.In the survey waters, Copepods was dominant in either species or individual numbers.The diversity (H')was 5.11 and the ratio of diversity to evenness (J) was 7.10,showing that the diversity of zooplankton was exceedingly high in the survey waters.Three zooplankton communities were clearly divided by systematical cluster analysis, indicating that the biotopes of these zooplankton communities may serve as the evidence for the basic status of distribution of water masses during the investigation.
